Ah...true on the vette's, vipers etc... the engines are "seated" at the factory, that is why they can run full synthetic. On the Ford oil....to save your butt in a warranty scuffle, it is better to use what they say...try going and buying a new engine on your nickle right now.... and these engines are very close tolerance, hence the 5W-20W synthetic blend...remember aluminum grows as it gets hot, and to use a higher viscosity oil is only going to hurt it. The guys and girls who design these high horsepower engines are no dummies, I am sure they destroyed quite a few during tests.
